X=7 All you need to do is combine like terms and then move the appropriate terms to the appropriate side.
Remark
Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.
Step One
Multiply both sides of the equation by 25
1 * (20 - t) = 4t - (3/5) * 25 Every part of the equation must be multiplied by 25
(20 - t) = 4t - 75/5 3*25/5 = 75/5
20 - t = 4t - 15 Add t to both sides
20 - t + t =4t + t - 15 Combine like terms
20 = 5t - 15 Add 15 to both sides
20 + 15 = 5t - 15 + 15 Combine like terms
35 = 5t Divide by 5
35/5 = 5t/5 Switch sides
t = 7 Answer
Answer:
3.5m
Step-by-step explanation:
Volume of pyramid = lwh÷3
25.77 = [(4.7)² × x] ÷ 3
25.77 × 3 = 22.09x
77.31 = 22.09x
x = 77.31 ÷ 22.09
= 3.49
= 3.5m
Walls = Plane
Intersection = line
Corner = Point
<u>We are given the equation:</u>

which can be rewritten as:
